Producing electronic music
All you need is a computer, a digital audio workstation (DAW), lots and lots of cool synths and samples (which can be made by yourself too), and creativity. Once you learn the basics of audioprogramming, mixing and mastering, there is no limit for your creativity. The best (and the addictive) thing about making music is that you can always improve and get better, it's an endless process. You can learn so many different things so many different ways, that I think it's the most interesting hobby ever.
The video above is probably the one of the best done electro house -tracks ever.
The kick in this song is so strong, the melodies are awesome and genius, and the drop is a true banger because it's so simple.
